Spring MVC,JdbcTemplate and Security Integration ClassNotFoundException: org.springframework.web.context.request.async.CallableProcessingInterceptor

I am implementing Spring MVC Spring Security MySQL Integration
My Stack Trace will look like this.

With reference to Spring Docs
http://docs.spring.io/spring-framework/docs/3.2.0.RC2/api/org/springframework/web/context/request/async/CallableProcessingInterceptor.html
Intercepts concurrent request handling, where the concurrent result is obtained by executing a Callable on behalf of the application with an AsyncTaskExecutor.
A CallableProcessingInterceptor is invoked before and after the invocation of the Callable task in the asynchronous thread, as well as on timeout from a container thread, or after completing for any reason including a timeout or network error.
As a general rule exceptions raised by interceptor methods will cause async processing to resume by dispatching back to the container and using the Exception instance as the concurrent result. Such exceptions will then be processed through the HandlerExceptionResolver mechanism.
The afterTimeout method can select a value to be used to resume processing.
Can anyone please explain and help me out of this.

Trace clearly shows, your application is not able to find CallableProcessingInterceptor class. Edit your pom with below dependency and check if it is working:
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-web</artifactId>
<version>3.2.0.RELEASE</version>
</dependency>

I have just verified. On a Spring 3.2.8 release, org/springframework/web/context/request/async/CallableProcessingInterceptor lies in spring-web-3.2.8.jar.
The error is :
...exception is java.lang.NoClassDefFoundError: org/springframework/web/context/request/async/CallableProcessingInterceptor
That proves that at run time spring-web.jar is not in classpath, or is not same version as other spring jars. A common cause for that when not using maven, is to declare the jars to the compiler or IDE, not include them in WEB-INF/lib in the war, and not to have them in Tomcat's classpath.
As you do not use maven, it looks like you are in a build and dependencies hell (name is mine). Either tomcat finds other jars (typically other versions of spring) in its classpath, or your build does not include (for any reason) spring-web-version.jar for correct version. This may be hard to fix, but you can try :
control is nothing looks wrong in your build process
control if the deployed application holds proper jars with proper version
strip down the application to remove parts until it works and re-add them one at a time in order to identify exactly what triggers the error
Or if you can do it, convert your application to use maven, and it will deal almost automatically with all those dependencies for you, warning you of incompatible versions.
But I'm afraid that I cannot do more for you here ...

This exception is caused due to Spring dependent jars missing or having conflict between versions of jars
Check whether you have spring-web-X.X.X (X.X.X is the required version depending on project) jar available on your build path/Maven dependency.
If there is any duplicate jar you need to remove it.

jcl-slf4j and axis 1.4 exception while substituting commons-logging

We are trying to substitute commons-logging + log4j by jcl-over-slf4j and logback (OK, at first we will try jcl-over-slf4j and log4j). Our application runs under WAS 8.0. Once the commons-logging jar has been erased and substituted by jcl-over-slf4j, slf4j and slf4j-log4j, we get this error message:

Is there some kind of incompatibility between commons-logging and its jcl-over-slf4j substitute?
We've checked some other projects, and it seems a common pattern: axis 1.4 + jcl-over-slf4j = exception.
[Note 1]
Classloader policy: tests.
In order to get commons-logging working with log4j at application level, we have assigned those libraries to the application (first we declare them both as "shared libraries", and we do the same with commons-logging.properties and log4j.properties files, then We assign them all to the application, and then we set the application's classloader policy to "Parent Last". This way, we force the application to load and use it's own copy of commons-logging, with its own configuration file, thus overcoming the commons-logging.properties included within WAS. This said, we have tried some "stupid" configurations, like make all the application use a single application classloader, or setting the web modules classloader policy to Parent Last. Such changes made no difference, as expected.
This far, we have found some nasty scenarios:
Axis + WAS logging facility (write all to SystemOut): OK, it works,
but we do not want everything written down to SystemOut!
Axis + commons-logging + log4j + their configuration files assigned
to the application at application classloader level,policy=Parent
Last. Some applications work, some others don't (theyshow messages
like the one quoted before).
jcl-over-slf4j + log4j + configuration file for log4j: Same result
as in point 2 of this list.
The last application we are dealing with right now, the application that fails with the excetions in the code block quoted previously: we have discovered that it only fails when we use configuration 3 (in this list), but it does not fail with configuration 2, which is very surprising and unexpected: in previous test with other applications, if the configuration fails with configuration 2, then it also fails with configuration 3.
[End of Note 1]
Any help will be welcome.

We have exactly the same Setup here:
WAS 8.0.0.9
log4j for logging
EAR containing jcl-over-slf4j, slf4j and slf4j-log4j
Axis 1.4
Classloader policy Parent Last and WAR policy Single class loader for application
As soon as axis-classes are loaded, some static-initializer-block gets executed and we get this Exception:
DiscoveryException: Class org.apache.commons.logging.impl.LogFactoryImpl does not implement org.apache.commons.logging.LogFactory
It seems like org.apache.commons.logging.LogFactory is loaded from jcl-over-slf4j and org.apache.commons.logging.impl.LogFactoryImpl is provided by WebSphere.
The only way it works for us, is to remove jcl-over-slf4j.jar from our EAR. Of course this way we might lose some Logs or find them in WebSphere SystemOut.log but at least 'it works'...

We encountered the same issues. Our solution is to tell commons-logging to use the slf4j factory implementation in our classloading context (in our case an ejb.jar).
To achieve this we simply added a commons-logging.properties file to our ejb.jar root folder with following content:
priority=1
org.apache.commons.logging.LogFactory=org.apache.commons.logging.impl.SLF4JLogFactory
This resolved the issue in our application.

Maybe this can help you. I was with a similar problem, and discovered a solution in SLF4J documentation.
http://slf4j.org/faq.html#excludingJCL
alternative 2) provided scope Commons-logging can be rather simply and
conveniently excluded as a dependency by declaring it in the provided
scope within the pom.xml file of your project. The actual
commons-logging classes would be provided by jcl-over-slf4j. This
translates into the following pom file snippet:
<dependency>
<groupId>commons-logging</groupId>
<artifactId>commons-logging</artifactId>
<version>1.1.1</version>
<scope>provided</scope>
</dependency>
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>jcl-over-slf4j</artifactId>
<version>1.7.21</version>
</dependency>
The first dependency declaration essentially states that
commons-logging will be "somehow" provided by your environment. The
second declaration includes jcl-over-slf4j into your project. As
jcl-over-slf4j is a perfect binary-compatible replacement for
commons-logging, the first assertion becomes true. Unfortunately,
while declaring commons-logging in the provided scope gets the job
done, your IDE, e.g. Eclipse, will still place commons-logging.jar on
your project's class path as seen by your IDE. You would need to make
sure that jcl-over-slf4j.jar is visible before commons-logging.jar by
your IDE.
SLF4J documentation gives more alternatives, this worked for me.

I have tried various ways of trying to include the apache httpclient library, but still no luck. Am I missing something?

A NoClassDefFoundError specifies that the particular library was available during compile time, but missing at runtime. You need to make sure that httpclient jar is present in your classpath. If it is present then it might be having a static initialization failure or is being loaded via a different classloader. You can go through this for any further info on how to debug a NoClassDefFoundError

Okay, after more tweaking I got it to successfully deploy the sample app. I needed to update the jar versions and modify the module xml in Jboss to point to org.apache.httpcomponents to use httpclient-4.2.1.jar, httpcore-4.2.1.jar and httpmime-4.2.1.jar.

Tomcat is just a servlet container and AFAIK, it does not support any kind of webservices by default.
You have to have the required libraries in your WEB-INF/lib or add it to tomcat lib folder and make use of it.
you are getting ClassNotFoundException as javax/ws/rs/Produces is not found in the classpath.
Deploy the REST implementation (Ex: Jersey) to server lib and restart your server.

Try removing annotations in your Axis2 service class. In our case, removing #Deprecated solved the error.

How to backport a 6.1.1 jsf portlet to get it running on a 6.1.0 liferay portal?

I'm trying to get an 6.1.1 Portlet running on a 6.1.0 Liferay CE Portal. The JSF Portlet uses the ServiceBuilder and a lot of other Util API classes of Liferay.
I thought the best idea would be to recompile the portlet with the correct liferay-plugins-sdk.
After downloading the 6.1.0 SDK, replacing it in the eclipse project, and rebuild it, I get
a couple of exceptions. They occur immediately after starting the server.

Has someone a good idea? I also posted this issue on the official forum , but maybe here I reach more people...
Here is the link to the forum: http://www.liferay.com/community/forums/-/message_boards/message/19124222
==== Update 1====
To solve the above exception I ran the service-builder within the 6.1.0 portlet again.
Now it is possible to start the server with the portlet, buuut
the portlet is not visible/available in the portal for adding in a page and I get the
following ClassNotFoundException: PortletBeanLocatorUtil:

Thanks for any suggestions!

It's probably easier to recompile the portlet in the 6.1.0 sdk. Especially when you use ServiceBuilder: you're running with a code generator that is probably relying on the runtime files that come matching runtime to generated code.
For pure JSR-286 portlets, they are easily compatible even across major versions. If you use more sophisticated code, e.g. ServiceBuilder or the API, lots of effort is taken to keep it compatible, but no guarantee can be given that it actually is binary compatible - sorry, that's life.
For Liferay's own plugins, you're asked to use matching versions - they're not tested between updates. And they most likely use ServiceBuilder and the API as well.
